Another very important function of thev device is'that-it may be utilized to lock the clencher-ring 7 in outermost position whenit .is supported against the Snap ring 8, as

or ring 7 partsare held when the tire is fully inlv lated, and the bolt 10 may be pressed tout- 'wardly juntil it projects sufficiently through the rim 4 to prevent the inward movement pensduringthe 4operation of a vehicle wheel' flatedand'- thus permit the ring 7 to 4slide rapid speed the snap=ring` 8 will 'bei. cen'\ trifugally thrown fromfthe rim 4T, and after. such occurrence the clencher-ring 7 will be free to shift laterallyoi of theirimltf thus releasing entirely the tire 5 which will'soonbe thrown froml thecwheel .with possibly reinjury to riders or occupants vofthe 'Any suitable means may be employed to offer sufficient friction to preventaccidental or too loose movement-orplay -of the bolt- 10 in`its respective bushing 3.
